Easily Seduced by for use and control

I was having a drink or two and was reading through personals on some site. One described straight couple looking for someone that would like to play with my tied spread eagle wife. I thought, hey that is kinky and something different. I replied and they shot me some photos of both of them together. I am shy and didn't want to send any. Their would be certain rules that I have to follow. She would be naked and bound spread eagle in the bed when I arrived. I wasn't allowed to put my penis inside of her. I was just interested to use her tits, finger her, fuck her with a dildo, or behind. She would be blindfolded. I was invited over. They guys was very nice, we sat and had some drinks, he then when back to the kitchen and stripped and came back in his underwear. Then he said oh there are a couple of things more. I don't want your dick in side of her. He handed me a dick chastity device and told me to put it on to make sure I didn't accidentally do anything wrong. Stripped naked, and then he handed me a dog/slave collar and then cuffs in leather. I went ahead with the game and yes it was hot. We went into the bedroom and I got on another side and he on the other. He started giving me orders like grab that tit, suck on that nipple, bite down a little and we played the game for hours. We spanked her and played with her body as she moaned and said more. I fucked her with toys and he fucked her with his cock. I was leaking from the device. It was a lot of fun. He was fucking her in the ass, calling her a slut and I was working over her dripping hole with a dildo that was strangely shaped until she begged for more, she came, he came and squired all over her chest. I must have dripped out all my cum as I leaked it all over. He did order me to clean it up with mouth. I left after a short nap - she never looked upon my face. We would play a lot like that and more.
